Partsam 4-Inch Round LED Trailer Tail Lights Kit, Red 4-Pack, 12-LED Sealed IP65

Partsam 4-inch round 12-LED sealed trailer lights are a compact, waterproof 3-in-1 lighting solution engineered for brake, turn and tail functions on 12V vehicles and trailers.

These Partsam lights combine a recessed flush-mount design with a sealed, impact-resistant housing and 12 bright LEDs behind a red lens to deliver reliable signaling and running illumination. Designed to accept a standard three-prong plug and supplied with grommets and pigtails, the kit installs quickly into 4-inch openings and tolerates exposure to dust, rain and road debris thanks to an IP65-rated seal.

How do these lights fit and connect to my trailer?

The lights are built for recessed flush mounting with an approx. 5-inch outer ring and a 4-inch inner cutout diameter, making them compatible with many common trailer openings. Each lamp includes a grommet and pigtail wiring harness and accepts a standard 3-prong plug for straightforward replacement or new installs.

• Recessed mount with included grommet for a snug, vibration-resistant fit
• White wire = ground; red = high/stop/turn; black = low/tail running
• Standard 3-prong plug compatibility for fast swap-outs
• Approximately 1 3/16" thickness for common mounting panels

How bright and durable are the LEDs?

Each lamp contains 12 LEDs that switch on faster and use less current than incandescent bulbs, offering clearer, quicker signaling. The sealed design resists impact and traps out water and dust, so the LEDs continue to perform in rough road and wet conditions.

• 12 bright diodes per unit for high-visibility stop/turn signals
• Water-tight sealed housing with IP65 resistance to elements
• Lower heat generation and reduced current draw compared with bulbs
• Impact-resistant construction to withstand shocks and vibration

Will these work with my vehicle's electrical system?

These lights are compatible with 12V DC systems and will operate across a wide 8–16V range, making them suitable for many trucks, trailers, RVs and utility vehicles. They accept standard trailer wiring functions—brake, turn and tail—so they integrate with most stock harnesses and controllers.

• Designed for 12V DC systems; functions across 8–16V input
• Three-wire hookup mirrors common trailer wiring conventions
• Works with trucks, trailers, RVs, UTVs and boats (12V systems)
• Plug-and-play compatibility with standard 3-prong trailer connectors

What should I expect during installation and maintenance?

Installation is typically quick: cut or confirm a 4-inch inner mounting hole, seat the grommet and wire the three conductors to the trailer harness. The sealed assembly requires minimal upkeep; occasional lens cleaning and wiring checks are usually all that’s needed.

• Quick recessed installation with included grommet and pigtails
• Simple three-wire connection—ground, high (stop/turn), low (tail)
• Low maintenance due to water-tight, dust-resistant sealing
• Recommended: check harness and connector condition periodically

Who is this for: This Partsam 4-pack is aimed at DIY trailer owners, fleet managers and anyone who needs a compact, durable replacement or upgrade for round tail lights. It’s a practical choice for trailers, small trucks, RVs, boats, UTVs and service vehicles that use 12V systems and benefit from faster, more efficient LED signaling without complicated rewiring.
